Grapefruit juice can affect how well some medicines work
Some medications need to be taken on an empty stomach, some only with a meal, but grapefruit can also be a huge no-no with certain medicines.
According to the Hippocratic Post, there are more than 50 medications that can possibly be altered by the citrus fruit.
How can a fruit affect medicine? Well, grapefruit has a compound which can mess with an enzyme in the small intestine. The small intestine is responsible for breaking down most of the medicines we take, so if you've taken certain medications and eaten grapefruit, the effects of the medicine could be too strong or not effective at all.
